LAM P H EATER.

SPECIFICATION forming part of Letters Patent No. 495,199, dated April11, 1893.

Application iiled December 29, 1892. Serial No. 456.626. (No modal.)

To all whom it may concern:

Be it known that I, CHARLES HEMJE, a citizen of the United States,residing at Annapo lis, inthe county of AuneArundel and State ofMaryland, have invented certain new and useful Improvements in LampHeaters; and I do declare the following to bea full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.l

My invention relates to improvements in heating or increasing thetemperature in rooms by means of lamp heaters, and the ob- Jects of myimprovement are, first, to create an increased draftin lamps andconsequently a better combustion; second, to utilize the heated airformed under the lamp shade and around the chimney, and superheating itby letting it pass over the top of the chimney; and third, by radiatingthe air so heated by radiation from und er a detlector, for heatingpurposes.

The invention consists in the construction of certain details andarrangement of parts as will be more fully described hereinafter andspecifically pointed out in the claims, reference being had to theaccompanying drawings and the letters ot' reference marked thereon.

Like letters indicate similar parts in the different figures of thedrawings, in which:

Figure l is a View of an ordinarylamp with my improved heating apparatusheld in position by means of a suitable tripod attached to the upper rimof the lamp shade. Fig. 2 is a modification of the heating apparatus,radiating the heated air through channels formed in its upper part, andbeing placed on a reversed tripod suspended from the top of the chimney.Fig. 3 is a modification of the heating apparatus, arranged so as tostand directly on the lamp shade,

With any ordinary lamp A,the air in the immediate vicinity of thechimney B andl under the shade S, is heated to a certain eX- teut, butthe effect of this is quickly lost in the surrounding cold air. Byplacing around the chimney B, and partly surrounding the same, a heatingshade or globe C, as shown in the accompanying views, the partly heatedair which has been formed beneath the shade S, is drawn upward asindicated by the arrows shown, (Fig. 1,) and in its upward path, isstill further heated or superheated by the heat of the chimney B, and onaccount of y the heating shade or globe C being contracted in sectionalarea, just above the top of the chimney B, the ascending, graduallyheated air passes directly over the top of the chimney B, Where it issuperheated, and after having attained the greatest possible degree ofheat, it is discharged or radiated through the circumferential openingformed by the upper flange of the heating shade or globe C with adeflector D.

The heating effect of this apparatus is instantaneous as soon as thelamp is lighted, and in a comparatively short time the temperature in amoderate sizedroom canbe raised from 100 to 12C above the normaltemperature.

It is not claimed that the invention takes the place of a stove, but itis a most valuable assistance in insufficiently heated rooms and in bedrooms and sick chambers which have no other means of heating; iteectually dispels all dampness and thoroughly dries the atmosphere,which is so very desirable and necessary to health, and this benefit,obtained without additional cost as to oil or fuel, would be lostwithout the use of the apparatus.

It will readily be seen, that for obtaining the best possible results,it is necessary that the heating shade or globe C should extend downwardover the top of the chimney B to such a depth that the heated air formedunder the lamp shade S is quickly and directly drawn into it withoutloss of heat and that its contraction just above the top of the chimneyB Will tend to still further increase the temperature of the ascendingair, as, at that point it is directly acted upon by the greater heatcoming from the flame. Similar to all other hot air heating apparatus,the force with which the heated air leaves the apparatus, dependsentirely on the temperature to which the air can be heated Within it.

The manner of attaching the heating shade or globe C to the lamp isshown in the various views of the drawings.

As shown in Fig. l, a tripod or other suitable arrangement, on which theheating shade or globe C stands, is attached with its legs on the upperrim of the lamp shade S; as shown in Fig. 2, the tripod is reversed andsuspended from the top of the lamp chimney B, while in Fig. 3 the tripodis dispensed with and the heating shade or globe C is made deep or highenough to stand directly on the top of the lamp shade S. For bracket orhanging lamps the heating globe can be suspended from above in anyconvenient manner.

The apparatus may be made of glass, porcelain, spun or stamped metal orany other suitable material, and for convenience of manufacture may bemade in two separate parts, the top or detlector D being, in that case,connected to the lower part or globe C in such a manner, as to form acircumferential opening for the discharge of the hot air.

To readily remove the apparatus from the lamp, when hot, it should beprovided at the top with a suitable eye d or its equivalent.

As shown in Fig. 2, the discharge ot' the hot air takes place through anumber of radiating channels, which may conveniently be formed bycorrugating the corresponding iianges of the upper and lower parts asshown, or by other suitable means.

While the apparatus can be used with any ordinary lamp, -the bestresults will be obtained from a center draft lamp, or from Argandburners when used with gas.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

Il. The combination of a lamp with a heating globe, suspended orsupported substantially as shown, the globe being contracted above thetop of the chimney, forming a neck from which a flange extendsoutwardly, and a deflector arranged above the iiange of the globe, thespace between the flange of .the globe and the deiiector containing anydeslred number of channels radiating from the neck toward the peripheryof the flange, substantially as and for the purpose set forth.

2. The combination ot a lamp with a heating globe, suspended orsupported substantially as shown, the globe being contracted above thetop of the chimney so as to form a neck from which a flange extendsoutwardly,

and a deflector, arranged so that it forms,

with the outwardly extending flange of the globe, a circumferentialopening for the escape of the hot air, substantially as described.

3. As a new article of manufacture theherein described heatingattachment for lamps or gas burners, consisting of a globe which 1scontracted at its upper end so as to form a neck, a plurality ofchannels radiating from said neck, a deiecting plate, and a holder bymeans of which the globe can be attached to the lamp, substantially asand for the purpose described.

In testimony whereof I afiix my signature 1n presence of two witnesses.

CHARLES HEMJE.
